Girls often stay up late, what effect will it have on their health?

The harm that women often stay up late will cause are: reproductive development, vision and endocrine disorders.

1, damage to eyes. Staying up late is the most harmful to vision, not just the appearance of "panda eye". Overloading the eyes for a long time will cause problems such as eye pain and dryness, and even make people suffer from dry eye. In addition, eye muscle fatigue can also lead to a temporary decline in vision, making people have blurred, distorted and deformed vision. Overwork caused by staying up late for a long time may also induce central retinitis, leading to a sudden drop in vision.

2, affecting fertility. Men and women of childbearing age, if they often stay up late, will affect the activity and quantity of male sperm; It will also affect the secretion of female hormones and the quality of eggs, and it will also easily affect the menstrual cycle, leading to endocrine disorders in the human body.

3, causing skin problems. It will lead to dry skin, long black spots and acne; 165438+ 0: 00 p.m. to 3: 00 a.m. the next day is the "beauty time" for detoxification of various organs of the body, and it is also the time when the human meridians run to the gallbladder and liver meridians. If these two organs don't get enough rest, they will appear on the skin, which is prone to problems such as rough skin, yellow face, long black spots and acne.

4, human immunity is reduced. Work at sunrise and rest at sunset. The metabolism of human biological clock is set according to the light and dark cycle of 12 hour. When this natural law is disturbed, it will seriously affect the normal operation of the immune system. Physical exhaustion will occur in human body, and trace elements such as minerals and vitamins will be consumed in large quantities, which will make human body in a serious sub-health state.

Decline of human immunity: fatigue, habitual cold, gastrointestinal infection, allergies, etc. On the second day after staying up late, I often have a headache at work or class, I can't concentrate, and even have a headache.
